Description

Elevator flat layer bistable state magnetic switch

Technical Field

The utility model relates to a magnetic switch technical field specifically is an elevator flat bed bistable state magnetic switch.

Background

The magnetic switch is divided into a single-pole single-throw (SPST) and a single-pole double-throw (SPDT) according to the output type, and is divided into a high alarm (anti-overflow) and a low alarm (anti-idle running) according to the purpose, but the existing magnetic switch has poor stability, and the whole structure is not beneficial to shock resistance, dust prevention and water prevention; in view of these drawbacks, it is necessary to design an elevator flat bistable magnetic switch.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an elevator flat bed bistable state magnetic switch, the switch stability is good, and overall structure is favorable to accomplishing shockproof, dustproof and waterproof.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides an elevator flat bed bistable state magnetic switch, includes PCB board, glass pipe, inert gas, magnet steel, wire and dry reed, the glass pipe is installed to PCB board top, just the glass pipe both ends are all inserted and are installed dry reed, two do not contact under the end initial condition that the dry reed stretched into the glass pipe inner chamber, the glass pipe inner chamber is filled with inert gas, the magnet steel is installed in the embedding of glass pipe top, just the wire is drawn forth to PCB board one side, the wire branch becomes two and corresponds a dry reed of connection respectively.

The utility model has the advantages that: add the magnet steel being close to glass pipe intermediate part position, put excitation magnet in glass pipe other one end, magnet lower extreme magnetic pole is placed according to the magnetic pole that corresponds the side magnet steel, when magnet from the top down moves, when the S utmost point is close to the S utmost point of magnet steel on the glass pipe, two dry reed contacts in the glass pipe are closed, the glass pipe switches on, glass pipe this moment is equated with a lead-through wire, when the S utmost point of magnet keeps away from the S utmost point of magnet steel, two dry reed contacts in the glass pipe break away from, this structure, put into putting into the copper pipe wholly, inside watering epoxy prevents to damage bistable state magnetic switch because of vibrating, then it is sealed with the copper pipe, be favorable to taking precautions against earthquakes, it is dustproof and waterproof, this structure stability is good simultaneously, overall structure is favorable to.

Drawings

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

FIG. 1 is a general plan view of the present invention;

FIG. 2 is a top view of the whole part of the present invention;

in the figure: 1. a PCB board; 2. a glass tube; 3. an inert gas; 4. magnetic steel; 5. a wire; 6. dry reed pieces.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1-2, an elevator flat bistable state magnetic switch, including PCB board 1, glass pipe 2, inert gas 3, magnet steel 4, wire 5 and dry reed 6, glass pipe 2 is installed at PCB board 1 top, and glass pipe 2 both ends are all inserted and are installed dry reed 6, two dry reed 6 stretch into and do not contact under the end initial state of 2 inner chambers of glass pipe, 2 inner chambers of glass pipe are filled with inert gas 3, 2 top embeddings of glass pipe are installed magnet steel 4, and 1 one side of PCB board is drawn forth wire 5, 5 branches of wire become two and correspond a dry reed 6 of connection respectively.

The utility model discloses a theory of operation: add magnet steel 4 in 2 intermediate parts of being close to glass pipe, put excitation magnet at 2 other ends of glass pipe, magnet lower extreme magnetic pole is placed according to the magnetic pole that corresponds side magnet steel 4, when magnet from the top down moves, when the S utmost point is close to magnet steel 4 'S on glass pipe 2S utmost point, two dry reed 6 contacts in glass pipe 2 are closed, glass pipe 2 switches on, glass pipe 2 this moment is equal to a lead-through wire, when magnet steel 4' S S utmost point was kept away from to the S utmost point of magnet, two dry reed 6 contacts in the glass pipe 2 break away from, the structure, put into wholly and put into the copper pipe, the inside watering epoxy prevents to damage bistable magnetic switch because of the shock, then it is sealed with the copper pipe, be favorable to taking precautions against earthquakes, it is dustproof and waterproof, this structure switch stability is good simultaneously, overall structure is favorable to taking.

The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best understand the invention for and utilize the invention. The present invention is limited only by the claims and their full scope and equivalents.
